Title: Caution: Win7 Security Update KB4054518
Post by: airnocker on May 14, 2018, 02:01:42 PM
I normally run my Win7 Pro CNC machine with no Internet connection but I made an very temporary exception recently and found this bit of trouble>

A few days ago I installed the Autoleveller software which needed to download an update to .NET and C++ Redistributable. So on May 8th, 2018 I connected an Ethernet cable to the Win7 PC and downloaded and installed these. No problem, Mach3 and the Autoleveller app worked just fine. Then I forgot and left the Win7 connected to the Internet for several hours while not using it. As I was getting ready to shut down the Win7 PC there was an MS message on the screen telling me updates were ready to install.  I thought, oh no, it detected MS updates were available.  I paused, then I clicked OK, the updates installed without issue and I shut down the PC and disconnected the Ethernet cable.

Several days later, I started the Win7 CNC PC, logged in, went to start Mach3 and about the time the Artsoft logo would appear, the PC rebooted. I went through this start-up scenario 3 times with the same results. I then disconnected the PC's parallel port cable to my C1R10 BOB with no difference. Then I Google'd this Win7/Mach3 behavior and saw a post on CNCZone.  https://www.cnczone.com/forums/mach-software-artsoft-software-/356934-beware-windows-7-update-kb4088875-2.html (https://www.cnczone.com/forums/mach-software-artsoft-software-/356934-beware-windows-7-update-kb4088875-2.html)

I went back to the Win7 PC and looked at the installed updates to see the recent updates. There were 8 updates installed dated today, May 11th, one was a "Security Update for Microsoft Windows (KB4054518)" the other 7 were just "Update for Microsoft Windows..." I uninstalled the "security" update, rebooted, confirmed it was removed and then Mach3 started and worked properly. I left the other 7 updates installed.

There was discussion that this recent security update had adverse interaction with Mach3's parallel port driver.  But all I found were MS KB posts from Oct/Nov 2017 https://support.microsoft.com/en-us/help/4054518/windows-7-update-kb4054518 (https://support.microsoft.com/en-us/help/4054518/windows-7-update-kb4054518) and this for information https://support.microsoft.com/en-us/help/4048957/windows-7-update-kb4048957 (https://support.microsoft.com/en-us/help/4048957/windows-7-update-kb4048957).

There is probably no ill effects by this KB if using a USB smooth stepper.

I don't think my Win7 PC was connected to the Internet for most of 2017 since prior Windows updates had 2016 dates.  Just beware.

Thank you for sharing. I will add that update to my list. So far, KB4093118 and KB4103718 have also caused the same issue with the parallel port.

Edit: June's KB284826 update also causes crashes for parallel port users.

It looks like KB4054518 is an old update (December 2017) that may have been replaced by the two I mentioned before (KB4093118 and KB4103718). I'll hang on to it in my notes in case others are the same boat as you, coming online and getting slammed with updates.

Thank you,
Bryanna
